' Application filed December l9, 1884. (N0 model) T0 at whom it mayconcern:

Be it known that I, LOUIS G. CLAUDE, a

.citizen of the United States, residing in the city, county, and Stateof New York, have invented certain new and useful Improvements in theManufacture of Horseshoes of Combined Iron and Steel, of which thefollowing is a specification.

This invention relates principally to the manufacture of horseshoes fromplates or bars of combined steel and iron, but is applicable also, inpart, to the manufacture of horseshoes from plates of all iron or allsteel.

Prior to this invention two general methods of manufacturing horseshoesby machinery have been used. The first method, which is the one'mostcommonly practiced, consists in rolling a bar of iron or steel, or bothcom bined, cutting the same into lengths, and bending the lengths intohorseshoe shape. The calks are usually formed in the rolling of the bar,and the creases are formed before the bar is bent.

The second method consists in rolling abar with longitudinal ribs toform the heel and toe calks and punching out from this rolled bar, in atransverse direction, bent blanks, which are afterward shaped andfinished to constitute the completed shoe. These bent blanks have solidcalks formed on them by being punched from the said longitudinal ribs.The completed shoe has the grain of the metal extending transversely ofit, resulting from the blank being struck transversely from the rolledbar. This transverse grain is a disadvantage, because of its weakeningthe sides of the shoe between the calks, where it is naturally weakest,owing to the thinness of the metal and the presence of the creases andnail-holes.

My present invention aims to provide for the manufacture, withoutbending, of shoes which shall have the grain of the metal extendinglongitudinally of them.

The principal distinguishing feature of my invention consists ,instamping out curved shoes from a bar or plate. in successive longitudinal series, the toe of one shoe being cut out adjacent to the heelsof the next.

I will proceed to describe in detail the preferred mode of practicing myinvention in iron, referring for that purpose to the acconr panyingdrawings.

Figure 1 is a plan of a portion of the rolled plate of iron and steelfrom which the shoes are struck out, the dark stripes of ruled linesthereon being designed to indicate the iron and the white stripes thesteel portions of the plate. Fig. 2 is a transverse section of theplate. Fig. 3 is a plan of the plate and female die, illustrating theoperation of stamping out the shoes. Fig. 4 is a similar viewillustrating a modified method of stamping out the shoes. Fig. 5 is avertical transverse section of the'st-amping-dies, cut on the line 5 5in Fig. 3. Fig. 6 is a plan of the roughly-formed shoe or shoe-blankafter being thus stamped out. Fig. 7 is an inverted plan of the samewith the calks applied to it. Fig. 8 is a trans verse section of a calk.Fig. 9 isa plan of the finished shoe. Fig. 10. is an inverted planthereof, and Fig. 11 is a side elevation thereof.

The remaining views illustrate modifications. Figs. 12 and 13 are sideelevations of p two different forms of shoe. Figs. 1.4, 15, and 16 areviews corresponding to Fig. 3, and showing modified methods of stampingout the shoe-blanks. Fig. 17 is a view of the shoeblank corresponding toFig. 6.

The flat bar or plate A (shown in Figs. 1 and 2) is made up of alternatestripes or portions of iron or steel. The center stripe, a, is of iron;each side of this are stripes b b of steel, and outside of these aremarginal or flank stripes c c' of iron. This plate may be produced inany way known to workers in iron and steel, as by rollingfrom an ingotor pile of combined iron and steel. It is preferably made according tothe method disclosed in my application for patent on improvements inbars of combined iron and steel and their manufacture executed by methis day, application No. 150,778, filedDecember 19, 1884.

In Figs. 3, 4., and 5, Bis the lower or female die, and in Fig. 5, G isthe upper or male die or punch for stamping out the shoe-blanks.

' These dies are made to cut out a blank having the outline of thefinished shoe or an outline closely approximating thereto. The die B ismade with a raised margin or flange, d, on each side to serve as a guideto the bar or manufacturing shoes of combined steel and 1 plate A, thusconstituting a sort of trough,

through which the plate is punching proceeds.

Fig. 3 shows clearly the preferred method of punching out the shoe-blanks. The dies are turned with the heels toward the operator, whofeeds along the plate and controls the operation of the press. Aftereach blank is punched out the operatormoves theplate forward just farenough to cover the die with whole metal from which to punch thesucceeding blank. The relation of the successive blanks to each other asthey are to be punched outof the bar is denoted by the dotted lines.

Fig. 4 shows a different way of feeding the bar during the punching,itbeing passed in the opposite direction through the dies. The dies areturned with the toe of the shoe toward the operator, the blanks beingstruck out heel foremost, insteadof toe foremost. The former method ispreferable, however.

Fig. 6 is a plan of one of the shoe-blanks thus punched out, lettered D.It has by preference the same outline as the finished shoe, so that nobending is necessary to complete it. It consists, mainly, of steel, thesteel portions b 0 extending from toe to heel down each lcgof the shoe,along the innerside thereof, with iron flanks c 0 along the outer sideof each leg of the shoe, and an iron center, a, be-

passed as the tween the steel portions. The steel portions 1) b impartstrength and rigidity to the shoe where strength is most needed. Theiron flanks afford a comparatively soft medium in which to form thecreases, and through which to punch the nail-holes, and the iron centeraffords a ductile portion from which to'form the toe-clip. The blank isformed with a slight projection, c, at the toe, punched from within thelimits of the iron center a, which furnishes sufficient metal forforming the toeclip.

Fig. 7 shows the blank the manufacture. The Fig. 7 has a toe calk,welded upon its under side. These are cut from a rolled bar of thecross-section shown in Fig. 8, preferably of steel, or having an edge orcore of steel. The shoe may then be finished in any known or practicableway, it be ing necessary to form the concave upon its upper side, at hin Fig. 9, to form the creases for the nail-heads i 2 Fig. 10, and toturn up the toe-clip j, Figs. 9-and 11. All these operations may beperformed simultaneously by the machine disclosed in my application,executed simultaneously herewith, for a patent on improvements inhorseshoemachines, application No. 151,131, filed December 26, 1884. Thefinal operation is the punching of the nail-holes, which is effected inany suitable p unchi ng-press.

Figs. 9, 19, and 11 show the finished shoe. This shoe is characterizedby having a parallel grain running from toe to heel, orlongitudinally ofthe shoe, in coutradistinction to a grain running in a curve around theshoe from one heel around to the other. The only in the next stage ofplain blank shown in f, and heelcalks g portion of the shoe where thegrain runs transversely to the outlines of the shoe is at the toe, andat this point the shoe is strengthened by the toeealk f, which extendstransversely of the grain.

The heel-calks instead of being welded on may be formed by turning downthe heels, as shown in Fig. 12.

The shoe may be made entirely without calks, if preferred, but in thiscase it is preferable to thicken the toe at its lower front edge, asshown in Fig. 13, where a similar beveled thickening is shown at theheel. This construction of shoe is best made from a plate havingtransverse ribs, as shown in Fig. 14:a method of manufacture, however,which I do not claim in my present application, it being made thesubject of another application for patent executed by me this day forimprovements in the manufacture of horseshoes with solid calks,application No. 150,889, filed December 20, 1884.

It will be observed from an inspection of Figs. 3 and 4 that the toe ofeach shoe-blank enters between the heels of the next, thus economizingwaste to the utmost. This is not, however, absolutely essential to myinvention, since every alternate blank might be reversed, as shown inFig. 15, thus bringing the blanks heel to heel and toe to toe; or, adouble row of blanks might be cut from the same plate, as shown in Fig.16.

I have said that the shoe-blank D is punched from the plate with thesame outline as the finished shoe, or approximately the same. It is notessential to my invention thatthe blank should have, by any means, theexact outline of the finished shoe, since it may be punched out with itslegs or heels spread considerably wider apart than they should be in theshoe, and be squeezed inward to the proper shape during the subsequentsteps in the manufacture. Fig. 17 shows a blank which is punched outwith its legs nearly straight and its heels considerably wider apartthan in the shoe. Before the shoe is finished it will be brought to theshape shown in dotted lines. This is best accomplished in the creasirig-machine, before referred to, where the shoe is gripped laterally byjaws, and these jaws in coming together will serve to force in the heelsof the shoe. It is always preferable for the shoeblank to he madcalittle wider than the 0c,

in order that the gripping-jaws may, by compressing the shoe laterally,gain a firm hold and force all the shoes to a uniform outline, ready forthe creasingdies.

I am aware of the method of manufacturing horseshoes disclosed inEnglish Patent No.

3,337, dated July 5, 1883, and I make no claim to anything contained inthat patent.

My invention possesses several important advantages over the method ofmanufacturing horseshoes bybending them from astraightl'iar, namely: Themanipulations are simpler and cheaper, and are effected with lesscomplicatcd machinery, and the metal is not subjected IIO to strain. Inthe-case of a shoe 'bent from a bar. of combined iron and steel,difficulty has been experienced from the liability of the iron and steelportions to separate, by reason of the strain imposed upon them inbending, a trouble which is entirely obviated by my invention.

I make no claim in this application to the finished shoe produced by mypresent invention, that being claimed in another application executed byme this day for improvements in horseshoes, application N 0. 151,042,filed December 23, 1884.

I claim as my invention- 1. The improvement in the manufacture ofhorseshoes, which consists in punching from a plate of rolled metal asuccession of curved blanks, their outline coinciding with orapproximating that of the finished shoe, and the plate being presentedto the punching-dies with the grain of the metal extendinglongitudinally of the shoe blank, whereby the blanks have a parallelgrain extending from toe to heel, substantially as set forth.

2. The improvement in the manufacture of horseshoes, which consists inpunching from a rolled plate having a longitudinal central stripe ofiron flanked by stripes of steel a suceession of curved blanks of ashape approximating that of a finished shoe, with the said stripe ofiron crossing the toe portion of each blank, substantially as set forth,whereby the subsequent formation of the toe-clip is facilitated.

3. The improvement in the manufacture of horseshoes, which consists inpunching from a rolled plate having a longitudinal stripe of ironflanked by steel a succession of curved blanks of ashape approximatingthat of a finished Shoe, the toe portion of each of which is formed withaprojection, e, the said blanks being cut with said stripes of ironcrossing their toe portions medially, substantially as set forth. 7

4. The improvement in the manufacture of horseshoes, which consists inpunching from a rolled plate having a central longitudinal stripe ofiron two parallel stripes of steel on opposite sides thereof, andopposite stripes of iron flanking the steel, a succession of shoeblanksof a shape approximating that of a finished shoe, with the said centralstripes of 6. The improvement in the manufacture of horseshoes, whichconsists in first punching out a curved shoe-blank from a rolled-plate,

with the grain extending longitudinally of the blank, and subsequentlyweldingatoe-calk to said 'blank transversely of the grain of the blank,substantially as set forth.

In witness whereof I have hereunto signed my name in the presence of twosubscribing witnesses. I
